Improve the realtime example by passing some data over the channel

[mdepot]

This is to suggest a minor improvement to the realtime example. Currently the /examples/README.md file says it "demonstrates the use of go channels to perform realtime communication with a Bubble Tea application."

Right now a channel is in use, however no data is being passed over it, so it's not really demonstrating how to update the model with something that was passed over a channel.

Instead of just counting the number of times that no data was sent, this example could be improved if it actually passed some sort of data in the structure, and then Update() could update the model with whatever was received through the channel, and then the View() could actually show that data as successfully arrived.

That sounds good to me. Feel free to open a PR to add that functionality.
